STEAM AND WATER SEPARATOR.

Specification of Letters Patent.

Patented Aug. 1, 1911.

Application filed May 4, 1910. Serial No. 559,298.

To all whom it may concern:

Be it known that I, FRIEDRICH WILI-IELM BORN, a subject of the King ofPrussia, residing at 1&3 Kantstrasse, Charlottenburg', Germany, haveinvented certain new and useful Improvements in Steam and aterSeparators; and I do hereby declare the following to be a full, clear,and exact description of the invention.

My invention relates to a device which is to be arranged within thesteam chamber of a steam boiler, by means of which the steam isseparated from the water in suspension therein before it passes away tobe used. In the case of locomotives for instance, the separator isprovided in the dome.

The invention consists in arranging within an annular chamber throughwhich the steam has to pass, a ring of blades, which as the steam passesthrough divide the latter into numerous small streams, the blades beingcurved so as to impart to the steam a screwlike motion of small pitch.The outer edges of the blades being situated at a suitable distance fromthe inner wall of the annular chamber.

In the accompanying drawings which illustrate by way ofeXample one formof this invention Figure 1 is a vertical longitudinal section; Fig. 2 isa plan view partly in section.

In carrying my invention into effect, the usual regulator head issurrounded steam tight by a casing a into which opens at one side, asteam supply pipe Z). To the depending end of the pipe Z) is secured bymeans of angle irons E, a pipe d of larger diameter and one end of thelarger pipe is reduced in size and connected to a water drain pipe cl.The latter when arranged above the water level in the boiler has adischarge flap 6 and is closed at its lower end as shown. The lower endmay however be left open in which case it dips into the water in theboiler or may in some other manner be adapted to permit the separatedwater to return to the boiler.

The steam on its way to the regulator is compelled to flow through anannular space between the pipes 79 and cl whereby it is subjected tocentrifugal action owing to the sharp changes of direction caused by a'ring of blades f splitting it up into many small streams.

At a suitable distance below the pipe 7) is provided a cone 9 fastenedto the pipe by means of brackets 0 which are bent outward to alsosupport a ring 79 the diameter of which is approximately intermediate ofthose of the pipes 25 and (Z. The ring p forms a partition separatingtwo annular spaces R and 1". The inner space 1" serves to lead theseparated steam direct to the regulator head, while the steam in theouter space R must first pass around the ring 7) and between thebrackets 0 before it unites with the steam in the inner space 1'. Theseparated Water flows down into the drain cl. The cone 9 may beperforated so as to allow the passage of steam, thrown through theperforations of the cone from below it, while water separating from thesteam flows down the cone.

It is essential that the steam should not be permitted to flowvertically from the top between the pipes Z) and (Z but enter betweenthem from a horizontal direction, and for this purpose a guard plate 7%is provided over the entrance E. Moreover it is necessary to insure thatthe wet steam shall advantageously impinge on the outermost bladesurfaces bounding against the inner wall of the pipe (Z. For thispurpose an exchangeable deflecting ring Z is fastened to the pipe 7)above the blades f. The apparatus is stayed by means of the supportingbracket 70, and may be inserted completely finished in the dome andconnected with the casing a. A. hole is provided on the lower side ofthe casing to allow of the passage of the regulator rod, the latterbeing provided with a sliding member a, to prevent the passage of steam.

I claim:

1. A steam and water separator comprising two pipes concentric one inthe other to form an annular space, curved blades arrangedcircumferentially in said space, the transverse section of the bladesbeing curved downwardly in the direction of the outer pine, acylindrical ring arranged between said pipes near the lower rim of theinner one and below the blades to divide the steam in two differentstreams before entering the outlet pipe, and a cone provided below theinner pipe, substantially as and for the purpose set forth.

2. A steam and water separator compris ing two pipes concentric one inthe other to form an annular space, curved blades ar-;

most surface of the blades, substantially as and for the purpose setforth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
